[IE11 issue only] TinyMCE behaves unexpectedly with new line if a text was pasted in that same line DescriptionIn the TinyMCE, while using IE11, when typing and reaching to the end of the line, the last part of the line is breaking and moving to the next line, instead of just the word which is exceeding the line length.
